Off topic?
I went up the BT tower when it still had a public gallery. I still have the brochure somewhere, what impressed me was the size of the power feed bus-bars. IIRC (unlikely) they had about 10 (now I'm guessing) 2ft width x 1inch thickness aluminium bars stacked so that there was a 1 inch gap between the bars. (Imagine a 90° change of direction of the bars)
A friend of mine lived adjacent to the tower and when the IRA bombed it, pieces were raining down on his house. He thought that the tower was going to fall on his house. A case of brown pyjamas maybe :(
Fun fact number two:
A WW2 aeroplane nerd told me that at the start of WW2 there were 20 anti-aircraft guns guarding the Scapa Flow and only six guns for the whole of London.
Fact number three:
I hate BT and will have nothing to do with them, bunch of (read the small print) crooks.
Biting the hand that feeds IT
